Hi Greyman. Are you connected to the fantastic wwiiaircraftperformance.org site? Thanks so much for all this valuable information, really makes research easier and more accurate to have access to the actual official tests. Rather than bore the message board I wondered if that P-39 information, especially the N tests, had been published before? 2012 on your site was the first time I had ever seen that report. Thx

Hi Greyman,
I'm keen to get in touch with you regarding RAF 8-gun fighter convergence. I undertsand you were (a few years back) looking for "official" RAF documentation on this issue, which is something I am also doing at the moment. Is there a way/ place we can discuss or share information on this?

Greyman ,nice to hear from you. Sorry I missed this and have taken so long to respond. In my copy of the Hurricane II Manual it lists 2 mods for the glycol header armour. The first is mod no 188, Armour forward of header tank 8.08 lbs and Mod 207 Armour forward of header tank introduced 7.14 lbs. Unfortunately in most restored Hurricanes this armour has been removed. However Squadron Signals Publications has an excellent picture of it on page 40 of "Hurricane Walk Around". It looks to be between 4 to 6 mm thick. Additionally the Cowling from the base of the windscreen to the back of the engine covering both the auxiliary fuel tank and the glycol header tank was 10 swg(gauge) duraluminum (1/8 inch thick). This is covered in "Knights of the Skies" by Michael C Fox. Send me your email if you want me to scan the picture and send it to you.
